RESTRAIN CABLE
For factory-installed lugs, install cable in order
listed and torque wire binding screw as
recommended on the faceplate and Table 1.

binding screws must be fully tightened before
installing top cables. Remove foam spacer
before installing cable. If not using all lug holes,
use bottom holes first and seat screws for
unused lug holes by screwing wire binding
screws down until seated.
